Should have added the example beforehand:

[root@kenji ~]# more nmap.scanned
# Nmap 6.00 scan initiated Mon May 21 16:56:39 2012 as: nmap -sS -p 80,442 -oG nmap.scanned 10.4.4.72
Host: 10.4.4.72 (kenji.infiltrated.net) Status: Up
Host: 10.4.4.72 (kenji.infiltrated.net) Ports: 80/open/tcp//http///, 442/closed/tcp//cvc_hostd///
# Nmap done at Mon May 21 16:56:41 2012 -- 1 IP address (1 host up) scanned in 2.17 seconds

[root@kenji ~]# awk '/http/{print $2","$5}' nmap.scanned | awk -F / '{print $1}'
10.4.4.72,80
